5.7 0r 6.1 with msd hemi 6 and carb

Hi RatPatrol them charts almost look like they are for a boosted motor to me because of the positive MAP readings , i've used plots for progamable ignition only, so they look different to this , so maybe i'm missing something.
Anyhow what people seem to be saying here is around 22 degress for wide open throttle max RPM with sequential injection , perhaps a little more for a carbed Hemi , maybe they need to be a bit richer to allow for less precise fuel distribution ' my guess ' .
I think safe AFR's on a carbed motor would be more like mid 12 to low 13 .
